“…A constant-voltage driving circuit is not advisable, as it would allow the current to change based on various external parameters and reduce the panel's lifespan. Alternatively, it is desirable to have a driver circuit that allows for light dimming by adjusting the driving current and is capable of adjusting the driving voltage to compensate for the reduction in current over time [33,34]. OLEDs, to be employed in lighting applications, must meet specific requirements, such as high brightness, high efficiency, low costs, low power consumption, and a long lifetime [35].…”

In academic research, OLEDs have exhibited rapid evolution thanks to the development of innovative materials, new device architectures, and optimized fabrication methods, achieving high performance in recent years. The numerous advantages that increasingly distinguish them from traditional light sources, such as a large and customizable emission area, color tunability, flexibility, and transparency, have positioned them as a promising candidate for various applications in the lighting market, including the residential, automotive, industrial, and agricultural sectors. However, despite these promising attributes, the widespread industrial production of OLEDs encounters significant challenges. Key considerations center around efficiency and lifetime. In the present review, after introducing the theoretical basis of OLEDs and summarizing the main performance developments in the industrial field, three crucial aspects enabling OLEDs to establish a competitive advantage in terms of performance and versatility are critically discussed: the quality and stability of the emitted light, with a specific focus on white light and its tunability; the transparency of both electrodes for the development of fully transparent and integrable devices; and the uniformity of emission over a large area.
